 former World is in considerable forwardness. Mr. Parkin- 

 3011 has solicited the favour of such remarks and specimens

M. Vogel, professor of painting in the Lyceum of War- 

 saw, in Poland, has announced a magnificent work for pub- 

 lication under the title of " Travels of a Painter through 

 Poland :" — It is to be filled with engravings of the scenery of 

 Poland, executed by M. Frey, from professor Vogel's draw- 

 ings ; and will also hand down to posterity engravings of 

 the monuments, palaces, and antiquities, &c. of that country, 

 hitherto so little known. This work of Messrs. Vogel and 

 Frey is the first attempt of the kind in Poland, and deserves' 

 the attention of all the friends of science throughout Europe. 

 Three parts are to be published yearly until completed ; and 

 the annual subscription is thirty-six rix dollars. The first 

 part is already published, and is a favourable specimen of 

 the progress of the arts in Poland.
